c. When installing outer rack oil seal, cover the end of rack with anOHP sheet [70 mm (2.76 in) × 100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d. Install end cover assembly to rack, move it to gear housing assembly.
5. Using a 45 mm (1.77 in) open head (suitable tool), tighten end cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6. After tightening end cover assembly, caulk cylinder at one point as shown in the figure using a punch. This will prevent end cover
from getting loose.
7. Install pinion assembly to gear housing assembly. CAUTION:
In order to protect oil seal from any damage, insert pinion
assembly out straightly.
8. Apply recommended fluid to O-ring. Install O-ring to rear cover.
9. Use a rear cover wrench (SST), install rear cover to gear hous- ing assembly.
10. Confirm projection on rear cover cap nearly fit with marking posi- tion on gear housing assembly.
11. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
12. Rotate pinion ten times whole range of rack so that parts get to fit with each other.

13. Measure pinion rotating torque within from –180 ° to +180 °,
make preload gauge (SST) and torque adapter (SST) in rack
neutral position, then hold preload gauge (SST) at maximum
torque.
14. After loosening adjusting screw once, tighten it again with torque of 5.4 N·m (0.55 kg-m, 48 in-lb). After that loosen it within 20 ° to
40 °.
15. Measure pinion rotating torque with torque adapter (SST) and preload gauge (SST), then confirm w hether it's reading is within
the specified value. If the r eading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the readi ng is still not within the speci-
fied value or the rotating torque of adjusting screw is less than 5
N·m (0.51 kg-m, 44 in-lb).
16. Turn pinion fully to the end of the left with inner socket to gear housing assembly.
17. Set dial gauge to rack as shown in the figure. Measure vertical movement of rack when pinion is turned counterclockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Check reading is within
the specified value. If reading is outside of the specification,
readjust screw angle with adjusting screw. If reading is still out-
side of specification, or if the rotating torque of adjusting screw is
less than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear
assembly.
18. Install large-diameter side of boot to gear housing assembly.
19. Install small-diameter side of boot to the mounting groove of inner socket boot.
20. Install boot clamp to the small-diameter side of boot.
21. Install boot clamp to the large-diameter side of boot.
